The Zeiss Ikon “C” designation in the C Sonnar T* 1.5/50 ZM name means both “compact” and “classic.” The lens design and aperture geometry reflect its predecessor from the 1930s, the Sonnar 1.5/50, which was the fastest standard lens of its time. The excellent flare control inherent of the Sonnar lens design is further optimized with the ZEISS T* anti-reflection coating. This lens stays true to its heritage, physically resembling the lenses of the past. With its fast aperture, taking photographs with a beautiful bokeh that reflects the ambiance of the golden age of rangefinder photography is as simple as pressing a button.
HIGH-SPEED LENS: Impressive photographs captured in low light always begin with a fast lens for a system or SLR camera. Because, a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.
IDEAL APERTURE PROPERTIES: The finely tuned features of the optical design on ZEISS ZM lenses ensure a spectacular bokeh, with the particularly harmonious effect of the blurred areas of the image. The ten diaphragm blades and the resulting, virtually circular aperture on ZEISS SLR lenses are crucial to favorable rendition of highlights in the foreground and background.
ROBUST DESIGN: The mount and control elements of all ZM lenses are made of metal and are designed for decades of intensive use. The high-quality craftsmanship of the all-metal mounts, the easy-to-grip metal focus and aperture ring, and the robust front bayonet and filter threads ensure an amazing photographic experience.
SMOOTH & PRECISE FOCUSING: Manually focusing a lens means controlling the image result from your fingertips. The good ergonomic design makes all the difference. The user-friendly focusing ring on ZEISS lenses with an ergonomic finger rest is perfect for fast, precise focusing. Changes are immediately visible in the viewfinder. The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive interaction with the focal plane.
ZEISS T* ANTI-REFLECTIVE COATING: The optical elements of ZEISS lenses feature T* anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavorable lighting conditions.
